How to prevent overwatering when growing vegetables on the balcony?

The temperature difference between morning and evening on the balcony is large, and during the day, the temperature difference between the three periods of morning, afternoon and evening will be relatively large, so you should avoid these times when you plant vegetables and water. This is because watering when the temperature difference is large, so that the value can not adapt quickly, resulting in a decrease in metabolism, a decrease in absorption capacity, and is not conducive to growth and development. Therefore, the best time to water is in the morning on a sunny day, at 10 to 11 o'clock.

Vegetable growth is manifested in the roots are very thin, especially the vegetable growth of melons and fruits will directly affect the flowering and fruiting later, such as tomatoes, cucumbers, peppers, eggplants, etc., the seedling stage must prevent the growth of the seedlings, to put it bluntly, let the seedling period grow more horizontally, less vertically, grow fat, don't grow too tall, so that the roots are very thick and strong, the root system is more developed, and then to the fruiting period can absorb more nutrients from the soil, transported to various parts, and the fruit can grow big and grow well.

If you want to grow vegetables on the balcony, you must make a waterproof layer of the balcony in advance, otherwise the roof of the balcony downstairs will become a drip hole. After making it waterproof, you can grow vegetables. However, it is necessary to pay attention to watering in the morning and evening, the soil layer of the balcony is not thick, and the water and fertilizer should be watered in time.

Generally, it is watered in the morning or evening, and the soil can only be watered when it is dry, and do not water if it is not dry. You can mix a little urine with a little water as fertilizer, up to a quarter, it's too thick to work. Pour on top of the soil next to the vegetables, not on the body.

This method is extremely simple, and the materials used are available in every family. As long as you fill the plastic bag with water, use a toothpick to make a small hole under it (it must not be too big), and then tie the mouth of the plastic bag tightly in the pot, at this time the water will flow out slowly, basically the plant can live very moist without watering for a few days.
